Hi Roy,
Not much help here I'm afraid. But I can't pass up a chance to talk
regular expressions.

Okay I am bad at regular expressions
Everyone is bad at regular expressions, even those of us who "like"
them. They have arcane rules (e.g., greedy vs reluctant quantifiers [1])
which requires a lot of attention to detail and, to top it all off, they
are pretty much impossible to debug.
For those who read [1] for the details, here's my guess as to why your
first attempt failed ...
In your case, the ".*" is greedy but I'm guessing the way the date stamp
#yyyyMMddHH# is implemented breaks the backtracking mechanism.

This StackOverflow question is kind of humorous if you don't really care
about the answer. If you do care (i.e., anyone who has to use regular
expressions), then you have to read it for the details and not the humor
(sorry):

that was a typo on my part in setting up the example.. I have pres$. After
testing a lot of things, I think junkF0..#yyyyMMddHH#pres$ works.

One problem is that you have at the end
pre$ rather than pres$
The premature $ would cause a failure.

Hi All:
Okay I am bad at regular expressions, and I am having problems giving
featureCollections the correct match to find the date for files that have
slightly different names. To simplify we want to have file that match
junkF0OF2013031206pres
junkF0RL2013031212pres
both included in the aggregation. I have tried junk*#yyyyMMddHH#pre$
junk.*#yyyyMMddHH#pre$ and a few other combinations and both have failed. Any
suggetions appreciated.
